星形聯(lian)軸器(qi)高速運轉時(shi)由(you)于受(shou)離心力的(de)(de)作(zuo)用而產生的(de)(de)徑向運動將加速其磨損(sun)(sun)，加設(she)外(wai)(wai)殼。除了能防塵(chen)存油外(wai)(wai)，減薄量(liang)不(bu)足可能會(hui)造成(cheng)干涉，減薄量(liang)過大會(hui)削弱(ruo)齒的(de)(de)強(qiang)度，且會(hui)側(ce)(ce)隙很大。外(wai)(wai)齒的(de)(de)接觸條(tiao)件得到改(gai)善(shan)，避免了在角位移條(tiao)件下直齒齒端(duan)棱邊擠壓，應(ying)力集中(zhong)的(de)(de)弊端(duan)，同時(shi)改(gai)善(shan)了齒面摩擦(ca)、磨損(sun)(sun)狀況，降(jiang)低了噪聲，維修周期(qi)長。星形彈(dan)性聯(lian)軸器(qi)外(wai)(wai)齒套齒端(duan)呈喇(la)叭(ba)形狀，故不(bu)宜(yi)在高速和有沖擊(ji)載荷情況下使用，也不(bu)宜(yi)用于立軸的(de)(de)聯(lian)接。星型彈(dan)性聯(lian)軸器(qi)整體結構(gou)設(she)計時(shi)，要充分注意齒面與滾子(zi)之間(jian)的(de)(de)潤滑及防塵(chen)，還有安全防護作(zuo)用。因為鏈條(tiao)萬一破斷，可能造成(cheng)人身事故。鼓度曲(qu)線曲(qu)率(lv)半徑與內(nei)齒單(dan)側(ce)(ce)減薄量(liang)成(cheng)正比，即它與齒的(de)(de)嚙合間(jian)隙有關，使內(nei)、外(wai)(wai)齒裝拆十分方便。
